Current behaviour

Bitcoin Core behaves unexpectedly or even crashes.

• getnewaddress "" unknown: "Error: No unknown addresses available. (code -12)"
• getrawchangeaddress unknown: "Error: No unknown addresses available. (code -12)"
• createmultisig 2 '["03789ed0bb717d88f7d321a368d905e7430207ebbd82bd342cf11ae157a7ace5fd", "03dbc6764b8884a92e871274b87583e6d5c2a58819473e17e107ef3f6aa5a61626"]' unknown: Bitcoin-Qt crashes with Assertion Error: "bitcoin-qt: outputtype.cpp:110: CTxDestination AddAndGetDestinationForScript(FillableSigningProvider&, const CScript&, OutputType): Assertion `false' failed."
• Bitcoin-Qt can be started with -addresstype=unknown or -changetype=unknown without any error message.

Expected behaviour

Bitcoin Core tells me something like "Unknown address type 'unknown' (code -5)", as if I used any type that is not legacy, p2sh-segwit, bech32, or bech32m.

Steps to reproduce

Open Bitcoin-Qt Console, create/open a wallet with appropriate settings if necessary, and run the commands above.

Or start it with -addresstype=unknown or -changetype=unknown.
